TOKYO and HSINCHU, Taiwan, Sept. 3, 2014 — (PRNewswire) — New Japan Radio Co., Ltd. (New JRC) and United Microelectronics Corporation (NYSE: UMC; TSE: 2303) ("UMC"), a leading global semiconductor foundry, today announced that they have begun supplying automotive ICs to major Tier-1 Japanese auto suppliers. Those analog ICs are incorporated into electronic control units (ECUs) adopted by major Japanese auto manufacturers. The power management IC (PMIC), designed by NJR and manufactured at UMC, has also been adopted by another international Tier-1 auto manufacturer. The milestone is significant as it demonstrates that UMC and NJR have met the high production quality and reliability standards for ICs used in automobiles, which are much more stringent than for traditional semiconductor manufacturing.

Mr. Takaaki Murata, NJR Director & Manager of its corporate office said, "NJR has been working hard with UMC to ensure that their production meets the rigorous requirements of Japanese car OEMs. We are pleased that UMC-made products are proven to meet those tough qualifications. I believe the combination of NJR's design know-how in automotive, leveraged with UMC's manufacturing expertise, will further open new markets in Japan and elsewhere."

"With NJR's guidance to successfully enter the tough Japanese automotive market, UMC has broadened its horizons in the automotive IC sector," said J H Shyu, senior vice president of Production and Operation Integration at UMC. "We have been able to produce high reliability wafers that conform to automotive safety requirements, with the low noise attribute of UMC's process technology resulting in highly accurate voltage control. We believe the benefits of UMC's robust manufacturing will help contribute to other auto OEMs as well."

NJR power management ICs (PMICs) are used to control battery voltage in cars, especially the idling stop control system. With the increasing silicon content in today's cars, vehicles are increasingly being considered an IT device, with almost $300 worth of semiconductor devices used in each auto. Every year, 80 million cars are manufactured worldwide, making automotive semiconductors a $24 billion market. Given automotive IC's high-profit and stable market, semiconductor manufacturers are seeing automotive as next opportunity following smartphones.
